Study Notes
Cerebral Angiography
- Purpose: Visualizes cerebral blood vessels, detects defects/narrowing/obstruction.
- Procedure: Iodine-based contrast dye injected into an artery (usually groin or neck). X-rays taken.
- Radiology Department: Conducted in a radiology department.
- Digital Subtraction Angiography: Hides bones and tissues, shows vessels clearly.
- Indications: Assessing brain blood flow, identifying aneurysms, defining tumor vascularity, treating blood clots/administering chemotherapy.
Pre-Procedure Considerations
- Pregnancy: Risk-benefit assessment for the fetus.
- Fasting: 6 hours prior; clear fluids allowed up to procedure in some cases.
- Allergies: Assess allergy history; steroids/antihistamines may be given for contrast allergies.
- Bleeding/Anticoagulants: Increased monitoring for blood clotting.
- Kidney Function: BUN and creatinine tests to evaluate kidney function to clear the dye.
- Sedation: Mild sedative for relaxation occasionally used.
Intra-Procedure Actions
- Positioning: Client on radiology table, head secured.
- Catheterization: Catheter placed in artery (groin/neck).
- Dye Injection: Dye injected, images taken.
- Catheter Removal: Catheter removed, bleeding controlled.
- Monitoring: Vital signs monitored continuously.
Post-Procedure Actions
- Clotting Monitoring: Closely monitor the insertion area for clotting.
- Movement Restrictions: Movement restrictions for a period depending on procedure.
- Neuro Assessments: Frequent neuro assessments.
- Vitals Monitoring: Constant monitoring of vital signs.
- Ice Pack: Apply ice pack to the insertion site.
- Fluid Intake: Encourage fluid intake to promote contrast excretion.
Complications
- Bleeding: Potential for bleeding and hematoma formation at the insertion site.
- Circulation Issues: Check affected extremity for circulation issues.
- Intervention: Apply pressure over artery if bleeding occurs.
Client Education
- Immobility: Remain still during the procedure.
- Voiding: Empty bladder before procedure.
- Post-Dye Sensation: Metallic taste and warmth are normal sensations after dye injection.
Cerebral Computed Tomography (CT) Scan
- Purpose: Provides cross-sectional images of the cranial cavity.
- Contrast Medium: Contrast medium can be used to enhance images.
- Indications: Identifying tumors/infarctions, abnormalities, monitoring treatment, guiding biopsies.
Pre-Procedure Considerations
- Pregnancy: Risk-benefit assessment for the fetus.
- Fasting: 4 hours prior to procedure; clear fluids may not be allowed.
- Allergies: Assess for shellfish or iodine allergies; consider further assessment.
- Kidney Function: BUN and creatinine tests to evaluate kidney function.
- Positioning: Pillows for back support to prevent pain.
- Metal Removal: Client must remove metal objects (jewelry, hairpins) to prevent interference.
Intra-Procedure Actions
- Positioning: Client lies supine, head stabilized.
- Sedation: Sedation is possible but not mandatory.
- Sounds: Expect various clicking sounds/vibrations.
Post-Procedure Actions
- Follow-up: No specific follow up required for a routine CT scan.
- Contrast Monitoring: Monitor for allergic reactions and changes to kidney function if contrast was used.
- Sedation Monitoring: Monitor client for stability incase sedation is used.
